No.
You would use different units of measurement. You would measure the size (circumference) of your waist (for trousers) in centimetres. You would not measure the distance to the moon in centimetres!

There should be no points after the decimal point.
With suitable use of the decimal point, any object can be measured in centimetres. Your palm is a few cm across. The length or height of a normal pet would be measured in cm. Peoples' height is measured in cm although they may be expressed in metres. Similarly, larger objects such as rooms may be measured in metres but, for precision, cm will be used.
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the required decimal representation is 127. If 127 mm were to be expressed in terms of some other unit of length then that unit of length should have been specified in the question.
One way is to multiply the numbers ignoring the decimal point. If the first multiplicand has d1 digits after the decimal point, and the second has d2 digits after the decimal point, then their product has (d1 + d2) digits after the decimal point.An alternative for the second stage is to estimate the answer to determine where the decimal point should go.
